Subject: Windows: Don't wildcard expand /? or -?
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=dee5e2cf7fa5cfc9c9407d66dae9169586041a51

Windows: Don't wildcard expand /? or -?

Even if there's a file called c:\a, we want /? to be preserved as
an option, not expanded to a filename.
